The traffic lights at a nearby intersection have gone haywire. The lights work, but there's nothing to control them.
The traffic is in trouble and it is now up to you to help direct traffic!
The object is simple: Keep your traffic moving as best as you can. But don't hold cars up too long! If your Rage-O-Meter becomes full then it's game over. Fire trucks, Police Cars and Ambulances will need to get quickly across your busy intersection too.
And if it all becomes to much then just enjoy creating traffic havoc by setting all the lights green!
